WILLIAM Y. GAMBEE, OF BROOKLYN, NEW YORK.

DUMPING-VEHICLE.

Application filed January 6, 1913.

To all whom it may concern Be it known that 1, WILLIAM Y. GAMBEE, acitizen of the United States, and a resident of Brooklyn, in the countyof Kings and State of New York, have invented certain new and usefulImprovements in Dumping- Vehicles, of which the following is aspecification.

The invention relates to improvements in vehicles or wagons for carryingrefuse, such as ashes, garbage and other materials gathered by thestreet cleaning departments of cities, as well as other materialsrequired to be conveyed, and more especially to a vehicle or wagonpossessing mechanical means for efl ecting the discharge of the materialfrom the vehicle or wagon.

I present my invention herein as embodied more particularly in amotor-vehicle adapted for the needs of street cleaning departments ofcities, but do not of course limit the invention to the nature of thematerial that may be carried.

One object of my invention is to provide a vehicle or wagon-body ofspecial construction adapted to the carrying of refuse and concealingthe same and of avoiding either the blowing of the refuse from thevehicle by wind or the leakage of material from .the vehicle around thelower edges of its body portion.

A further purpose of the invention is to provide a vehicle having anendless carrier of special construction constituting the bottom of thevehicle body and arran ed to be operated by the motor of the ve icle forefiecting the discharge of the load. The endless carrier extends thefull length and width of the vehicle-body and is of such durableconstruction that it may be safely depended upon for supporting anddischarging heavy loads, and the construction of the carrier is suchthat it may be readily operated to discharge the load without imposingundue strain on the engine or motor or such other power as may beapplied for eflecting the travel of the upper side of the carrier towardthe discharge end of the vehicle body.

The invention will be fully understood from the detailed descriptionhereinafter presented reference being had to the accompanying rawlnigs,in which:

hicle constructed in accordance with and embodying the invention, one ofthe side curtains above the upper edge of the vehiclebody being shown ina partly open position; Fig. 2 is a longitudinal section on a largerscale and partly broken away, through the body portion of the vehicle onthe dotted line 22 of Fig. 3; Fig. 3 is a vertical transverse sectionthrough the same on the dotted line 33 of Fig. 1; Fig. 4 is a horizontalsection through a portion of the vehicle taken on the dotted line H ofFig. 1; Fig. 5 is a top view; partly broken away, of the side sills ofthe vehicle and presents in top elevation the endless carrier which Iapply to the body of the vehicle as the bottom thereof; Fig. 6 is ahorizontal section through a portion of the vehicle body, partly brokenaway, taken on the dotted line 6-6 of Fig. 2; Fig. 7 is a top view,partly broken away, of the endless carrier and its supporting mechanism;and Fig. 8 is an enlarged vertical longitudinal section through aportion of the carrier and connecting parts taken on the dotted line 88of Fig. 5.

In the drawings 10 designates the vehicle body as a whole, 11 the sidesills of the vehicle, 12 the usual supporting wheels, and 13 the usualmotor features not necessary to describe, the same being common to motorvehicles and not per se claimed by me.

The body 10 will preferably be formed of sheet metal and comprises sides14, a front end 15 and a rear door or gate 16 hinged at its upper end,as at 17 and adapted to be secured in closed position by any convenientlatching means 18.

The sides 14 incline downwardly and inwardly, as shown in Fig. 3 and arestrengthened by vertical T-bars 19 secured thereto and at their lowerends to the side sills 11. The sheet metal sides 14 have along theirlower portions supplemental sideplates 20, between which and the mainsides 14; are spaces or chambers 21 (Fig. 3) for certain operativefeatures hereinafter described.

The front plate 15 of the vehicle body inclines downwardly and inwardly(Fig. 2) and has strengthening T-bars 22 and along its lower portion asupplemental plate 23 between which and the main front plate 15 is aspace or'chamber 24, for the purpose hereinafter described.

' rods 34, which superimposed structure forming an upper extensionthereof and comprising a roof 29, ends 30 and side curtains 31 securedon spring curtain-rollers 32 (Fig. 3) of usual type and which curtainsmay be raised or lowered at will. It is the intention that the curtains31 shall be in their lower closed position during the travel of thevehicle, aftena load has been gathered, so as to conceal the refuse inthe vehicle-body and prevent the wind from blowing particles thereofabout, and in the use of the vehicle it is the purpose that only suchcurtain as may be necessary shall be in its upper or open position topermit the dumping of cans into the vehicle-body, thus during thegathering of refuse the curtains being employed to as far as possibleconceal the refuse in the vehicle-body and prevent particles thereoffrom being blown about.

The bottom or bed of the vehicle body comprises an endless travelingbelt 33 extending the full length and Width of said body and preferablyformed of a good quality of rubber, as shown in Fig. 8, having embeddedin it parallel transverse metal are reasonably close together and proect at-their ends beyond the side edges of the belt 33 to receive thelinks of the sprocket chains 35, as represented more clearly in Fig. 7.The sprocket chains 35, one being at each side edge of the belt, aremounted on sprocket wheels 36 secured upon the front and rear shafts 37carrying, between the sprocket wheels, rollers or drums 38 upon which ismounted an endless chain of metal rollers 40 whose ends are connectedtogether by chains 41 carrying at the joints of their links studs 42which enter the open ends of the hollow metal rollers 40 and permit saidrollers to have freedom for rotary movement thereon. Immediately belowthe upper side of the chain of rollers 40 is provided a frame composedof longitudinal bars 43 and transverse bars 44, shown by dotted lines inFig. 5, for firmly supporting said side of the chain and the upper sideof the belt 33 superimposed on said chain. The

' longitudinal bars 43 are supported by the transverse bars 44 and thebars 44 are, at their ends, secured to the side sills 11, as clearlyrepresented in Figs. 2 and 3. During the travel of the belt 33 it isclose against the transverse rollers 40, as shown in Fig. 8, and causessaid rollers, as a chain, to travel on the drums 38 and also to rotateindividually on the studs 42, thereby avoiding excessive frictionbetween the belt 33 and chain of rollers 40, and permitting said rollersto at all times cooperate with the belt both as to its traveling motionand its proper support. The belt 33 is driven through the chains 35 fromthe sprocket wheels 36, and the chain of rollers 40 has only suchmovement imparted to it as it receives from the belt 33 and plainsurfaces of the drums 38. The rollers 40 ride on the drums 38 andlongitudinal bars 43 and aid materially to the efficient action of thebelt 33. The shaft of the front sprocket wheels 36 is mounted at itsends in adjustable bearings 45 (Fig. 4) so that the belt 33 and chain ofrollers 40 may be kept taut. The bearings 45 may be of any appropriateconstruction, but I illustrate them as being formed on sliding barswhich are adjustable by means of bolts 46. I do not, however, limit theinvention to any special means for tightening the belt 33 and chain ofrollers 40. On the outer end of the shaft of the front sprocket wheels36 is secured a gear wheel 47 through which said shaft and the sprocketwheels thereon may be driven by any suitable power. I shall preferablydrive the shaft 37 and the front sprocket wheels 36 by power from themotor carried by the vehicle, and this power may be transmitted to thegear wheel 47 through a sprocket chain 48 and pinion wheel ,49, the

latter being in mesh with the gear wheel 47.

The power will be transmitted to the sprocket chain 48 from the usualshaft 50 provided on motor vehicles and from which, through a chain 51,power is transmitted to the driving axle of the vehicle. \Vhen thevehicle is in motion power should not be transmitted to the sprocketchain 48, and when the vehicle is at rest and it is desired to dischargethe load, the usual motor will be kept in motion, as is common practice,and the power therefrom will be cut off from the driving chain or chains51, and by means of a clutch member 52,-t ransmitted to the sprocketchain 48 andby said chain to the pinion wheel 49, gear wheel 47 andfront shaft 37. The clutch member 52 may be of any of the many kindscommonly used and may be operated from the front of the vehicle body bymeans of a crank or handle 53. I do not limit my invention to anyspecial power devices for operating the belt 33, since obviously thesewill vary in accordance with the nature and size of the motor vehicleand other conditions. I therefore indicate diagrammatically merely thatit is my purpose to operate the belt 33 to discharge its load by powerobtained from the usual motor for driving the vehicle.

One important feature of my invention relates to the provision of meansfor preventing leakage along the lower edges of the vehicle body, and tothis end I provide a three-sided or U shaped' frame 54 extending alongthe opposite sides and front end of the vehicle body, the front end ofsaid frame being within the space 24 formed in the front of said bodyand the sides of said frame being in the spaces or chambers 21 formedbetween the plates 14, 20 of the sides of said body, as clearlyrepresented in Figs. 2, 3 and 6. The frame 54 is suspended by pivotedlinks 55 and has secured to it, along its entire length, a strip ofrubber 56 which is of angle shape in cross-section and has itshorizontal member extended inwardly upon the side and front end portionsof the belt 33. The strip of rubber 56 is a sealing strip for engagingthe upper surface of the belt 33 and preventing; during the travel ofthe wagon any leakage along the sides or front end of the vehicle body.The rubber strip 28' carried by the plate 26 forming a part of the reargate 16 is also a sealing strip and it, by its engagement with therubber belt 33, prevents leakage" from the wagon body at the rear endthereof. The strips 28, 56 become pressed closely against the surface ofthe belt 33 by the closing of the gate 16'. The rear ends of the sidemembers of the frame 54 normally stand in the path of the gate 16' (Fig.6), and when the gate is closed, it will press against said ends of saidmembers of the frame 54 and cause said frame to move inwardly to theslight extent required for carrying the sealing strip 56 firmly againstthe belt 33. When the wagon is to discharge its load and the gate 16 isopen, the traveling movement of the belt 33 to carry the load rearwardlyand eject the same from the vehicle body, will by its frictionalengagement with the strip 56, cause the frame 54 to move slightlyrearwardly and upwardly, said frame being suspended by pivoted links,and at such time the strip 56 will not act materially to retard thetraveling action of the belt 33. The slight movement rearwardly of theframe 54 by the action of the traveling belt 33, causes the rear ends ofthe side members of the frame 54 to project rearwardly to a slightextent in the path of the rear gate 16. After the load has beendischarged and the gate 16 1s again closed, it will, during its finalclosing movement, press against the rear ends of the side members of theframe 54 and move said frame inwardly, with the result of causing thesealing strip 56 to be again depressed against the side and front edgeportions of the belt 33. The frame 54 with its supporting links, bybeing confined within the spaces or chambers 21, 24, are protected frominjury by the load that may be placed in the vehicle body, and hence maybe kept in 0perative condition without special care and withoutinconvenience to the loading of the vehicle. The sealing strip 28 iswithin the chamber 27 formed between the two plates of the rear gate 16,and the sealing strip 56 is substantially'confined and concealed withinthe chambers 21, 24 formed along the sides and front of the vehiclebody. The sealing strips 28, 56 are desirable of use whether the vehicleis being employed for carrying either dry or wet refuse, since in eitherevent said strips prevent the sifting out or leakage of the refusearound the'lower edges of the sides and ends of the vehicle body.

The method of employing my invention will be understood from theforegoing descriptionwithout further detailed explana tion. vehicle bodyfrom over the side edges thereof, a curtain or curtains 31 being raisedto permit cans or barrels being tilted to discharge their contents intothe vehicle body. It is my purpose that the curtains 31 shall bekept-down to as great an extent as possible so as to conceal thecontents of the vehicle and prevent wind from blowing the same about.The belt 33 forms the bottom of the vehicle body and receives upon itthe load of material. When it is desired to discharge the load from thevehicle body the rear end gate 16 will be opened and power will beapplied either from the engine of the motor vehicle or other source toeffect a traveling movement of the upper side of the belt 33 toward therear end of the vehicle body, and this traveling movement of said beltwill cause the load to be discharged, as will be obvious. One of themain features of the present invention is the provision of an entirelyefficient and durable movable bottom for the vehicle body, this bottomcomprising the belt 33, supporting chain of rollers 40, and supportingframe comprisingthe longitudinal bars 43 and transverse bars 44 forsupporting the upper sides of the chain of rollers and belt 33. Theconstruction' presented by me is adapted for the carrying of heavy loadsof refuse and of being employed by the street cleaning de- The refusewill be thrown into thepartments of cities for conveying refuse to itsplace of deposit and there discharging the same with the minimum laborand expense.

I do not limit my invention to all of the details of for andconstruction presented in the drawings'and hereinbefore described, sinceI am aware that changes may be made in the detail of form andconstruction without departing from the spirit of my invention.
